Question

9. An auto driver travelled a distance of 60 km at a speed of 40 km/hr and another distance of 50 km at a speed of 30 km/hr. Find his average speed for the whole journey.​​

Answer 1

Step-by-step explanation:

given 1st distance =60km

time =40km/hr (1hr=60min)

speed =distance/time =60/2400 =0.025

2nd distance =50km

time 2=30km/hr

speed=distance/time =50/30×60=50/90=0.555

average =0.025+0.555=0.58
